“In the introduction to the judgment of the stars, Dariot presents questionnaire themes with simplicity. Each area of life is reviewed. Among the treasures contained in this text, the discovery of the true ruler of a house (its almuten) is not the least.”

In his work Ad Astrorum judicia facilis introductio first published in Lyon in 1557, Claude Dariot (1533–1594) blurs the boundaries between science and magic by discussing the effects of the movements of the planets and stars on certain illnesses and expressing his belief in astrologically favorable days for the preparation of remedies and for carrying out certain surgical procedures.

Claude Dariot (1533-1594), a physicist born in Beaune, set out the general principles of astrology and the rules of solar astrology, including the influence of the planets on daily terrestrial events. His treatise contains innovative ideas for the time: Dariot added to the traditional four elements (Water, Air, Fire, Earth), the three alchemical principles (Mercury, Sulfur, and Salt). According to him, these three principles form the basis of all beings. At the time of printing, the book had a sheet with instructions for mounting the volvelles and another with the uncut moving parts; in this copy, the instructions have fortunately been preserved and glued to the bottom of page 11 with the three scrolls mounted and functional.

Extremely rare first edition, complete with the 3 volvelles and their moving parts.
